Abstract:

Articles comprising a substrate and a first layer on a major surface thereof, wherein the first layer has a first random, nanostructured surface, and wherein the first layer has an average thickness up to 0.5 micrometer. Embodiments of the articles are useful, for example, for display applications (e.g., liquid crystal displays (LCD), light emitting diode (LED) displays, or plasma displays); light extraction; electromagnetic interference (EMI) shielding, ophthalmic lenses; face shielding lenses or films; window films; antireflection for construction applications; and, construction applications or traffic signs.

US Classification:

428144

Abstract:

Articles comprising a substrate, a first layer comprising polymeric material with nanoparticles protruding from a major surface thereof, and away from the substrate, and a second layer having major surface is a first nanostructured. Embodiments of the articles are useful for display applications (e.g., liquid crystal displays (LCD), light emitting diode (LED) displays, or plasma displays); light extraction; electromagnetic interference (EMI) shielding, ophthalmic lenses; face shielding lenses or films; window films; antireflection for construction applications; and, construction applications or traffic signs.

Abstract:

An adhesive composition is described comprising unpolymerized cyclic olefin, a ring opening metathesis polymerization (ROMP) catalyst or precatalyst thereof, and one or more adhesion promoter polymers. In one embodiment, the adhesion promoter is a polyolefin comprising maleic anhydride or silicon-containing moieties. In one embodiment, a combination of at least one polymeric polyisocyanate and at least one polyolefin comprising maleic anhydride or silicon-containing moieties provides a synergistic improvement. In another embodiment, a polymeric polyisocyanate adhesion promoter comprising oxygen atoms in the backbone has been found useful for bonding substrates such as polyamide, polyether ether ketone, or polyether imide. Also described are methods of bonding a substrate and articles, such as an electric battery cold plate assembly.

H01M 50/193

Abstract:

A composition is described comprising a cyclic olefin; a ring opening metathesis polymerization catalyst; and at least 40 wt. % of thermally conductive particles. The thermally conductive particles are selected such that the composition after curing has a thermal conductivity of at least 1W/M*K. In one embodiment, the thermally conductive particle comprises a combination of smaller and larger thermally conductive particles. In another embodiment, the thermally conductive particles comprise boron nitride particles. Also described are (e.g. structural) adhesives, methods of bonding and articles.
